7 Pros of Flask

1. Lightweight: Flask is a lightweight web framework that does not have too much overhead and is simple to learn and work with.
2. Flexible: Flask offers a modular architecture that allows developers to select the pieces that they need for their own project, thus delivering a better and more customized application.
3. Flexible: Flask is very scalable so that applications can scale to many requests at the same time without compromising on performance.
4. Extensible: Flask offers numerous extensions and libraries that you can add to your project to get even more functionality and save development time.
5. Simple and quick to learn: Flask syntax is easy to understand and use, making it perfect for beginners who want to quickly develop web applications.
6. Documented: Flask has extensive documentation and a large developer community, making it easy to get help and support.
7. Python integration: Flask uses Python, which is a very easy-to-read programming language. This integration gives programmers the ability to use the power of Python in developing web applications.
7 Cons of Flask

1. Lack of inbuilt capabilities: Flask is a micro-framework so it doesn’t include all the functionality that you might expect with a larger framework such as Django. Developers may need to use third-party extensions or libraries to implement some of these features.
2. Higher learning curve for more advanced applications: While Flask is a simple platform to use, developing more advanced applications can require additional web development principles and other frameworks or libraries.
3. Low default security options: Flask provides minimal security options, but you have to learn the flaws and take additional precautions to make your app secure.
4. No standardization: Since Flask encourages development by default, it is possible that developers have different approaches and design for developing their code, which can cause conflicts between Flask projects and make it more challenging for the new developers to absorb codebases.
5. Very limited support for large-scale apps: Flask can be scaled, but may not be suitable for very large, complex applications that need advanced functionality and big performance optimizations.
6. Dependency management: Flask Dependencies are difficult to maintain, especially when there are multiple extensions and libraries which may need to be managed simultaneously.
7. Limited native database support: Flask supports various databases with extensions, but it doesn’t have an embedded database abstraction layer like other frameworks, which means that developers need to work around database interactions themselves.
